engine trouble picking-up from idle
My 1968 MB 250 SE (2.495 cc, 6 cil. line, mech injection) has trouble picking-up after runing idle for some time. In fact the engine stops imidiately when i'm touching or even looking at the accelerator... The engine runs fine during riding and it runs idle very smooth as well. Just the picking-up is the problem.
The problem only occurs when the engine is warm - cold it's picking-up fine.
Could anybody tell me where to look first? Or probably someone even knows what the trouble is.
Many thanks and best regards,
The Hague, Netherlands
